Climate 

The area is highly seasonal:

• Mid December - February is the peak season: deciduous trees lose their leaves and it is becomes increasingly easy to observe birds and other animals; it is also relatively cool.
• March - May can feel the hottest time of year (but remember the forest is much cooler than the city). Many birds are nesting at this time and mammals can be seen leaving cover in search of water.
• Mid May - June see the start of the rains: this is usually the best time of year to come and see clouds of butterflies and watch the forest green-up after the dry season. Many of the trees flower and start to fruit: food for animals and birds.
• July - September: is the peak rainy season - the river is at its highest, sometimes reaching and flooding the roads. Visitors should be aware that certain paths cannot be negotiated at this time of the year. On the positive side, many trees, shrubs, gingers and orchids are in flower and this is the time to absorb the atmosphere of the 'steaming jungle' (biologists of course will always feel in their element).
• October - early December: with decreasing rains and temperatures, some visitors argue that this is an excellent time to visit Vietnam in general. In the park, the forest is still verdant and the rapids are vigorous.
